So I have the most bizarre issue happening and I don't know what to do. Google directed me to quite a few years old threads with the same issue, but surprise surprise, none of them end with OP returning to state what the issue was or how they fixed it.
I just got a new custom PC from cyberpower. It replaced my old rig (gtx 980 i54690k). It is a ryzen 3700 rtx 2070 super. Now, originally the GPU failed after 2 days, so I RMA the whole machine, they determined faulty video card and replaced it. Not sure if that has anything to do with this new issue.
The PC is hooked up to my TV, about 9 feet away. The issue is, when I stand up from the couch and generate a little static electricity and my feet hit the rug, the mouse/keyboard disconnect and immediately reconnect. Plugged into a surge protector on a grounded outlet (I know it's grounded for a fact) and the computer sits on hardwood, about a foot from the area rug. The rgb lights on the mouse and kb blink off then on, and I get the windows usb connection sound. Even if I place the kb and mouse over by the computer, 9 feet away, this still happens. It's just the damnedest thing. I called tech support and they were just as puzzled as I was. My old machine was plugged into the exact same set-up with no issue, and my spouses machine is hooked up on the other side of the room. I've tried different outlets, different keyboard and mouse, even ran an extension cord to the grounded outlets in the kitchen. Same thing. Can anybody help me with this? It's really damn annoying, and I know I'm not the first person with this issues, as evidenced by 8 year old forum threads describing the same thing. I am completely stumped here. At first I thought standing up was vibrating the case a little and maybe it was a loose header connection or something, but after hours of testing, I've determined it only happens if there's enough static to generate an audible little zap when I stand up. Nothing wireless, all wired. I do use usb extension cables, as I always have. But even removing them from the equation does not mitigate the problem.
